Preliminary evaluation of hBD3-mediated autophagy inhibition in rat NEC model. The expression of autophagy-related proteins LC3, p62 and Beclin1 in the ileum of rats among four groups was assessed by western blotting, the LC3II/LC3I ratio and Beclin1 expression was analyzed. (A) Kaplan Meier survival analysis was used to identify the differences of survival time in groups. (B) NEC pathological score was conducted in each group by a pathologist independently and compared with other groups as indicated. (C) Rats were intraperitoneal injected with BrdU 18 h before killing and immunostained with BrdU antibody to measure the enterocyte migration (D, scale bar, 50 μm). The migration distance (E) and mobility (F) were evaluated. ZO-1 and occludin were immunostained on the sections of the terminal ileum from rats among different groups (G, scale bar, 50 μm). Data was expressed as mean ± SD from three independent experiments and representative images were presented.
